Chemistry - Metallurgy Question with Solution | TestHub
Consider the following statement -
(I) Impure nickel is purified by Van Arkel method
(II) Anglesite and Cerussite are the ore of same metal
(III) Matte is a mixture of (small amount)
(IV) In hydrometallurgy, Zn is used as an oxidizing agent in the purification of Ag from If ' T ' is for true statement and ' F ' for false statement then select CORRECT option :-
Options:
Answer:
Solution:
Explain the question: Identify the correct True/False sequence for four metallurgical statements.
Concept: Refining, Ores, and Extraction Principles.
Solution:
(I) False: Nickel is purified by Mond's Process. Van Arkel is used for Zr or Ti.
(II) True: Anglesite (PbSO₄) and Cerussite (PbCO₃) are both ores of Lead (Pb).
(III) True: Copper matte is indeed molten Cu₂S with a small amount of FeS.
(IV) False: Zinc acts as a reducing agent (displaces Ag), not an oxidizing agent.
Final Answer: Option B (F T T F).
